List of parameters used in evaluating the numerical simulation of System (1) and (2).

Notation	Description	Values
${\gamma }_0\left({\gamma }_1\right)$	COVID-19 recovery rate in the case of a lack of healthcare capacity (in the case of excessive healthcare). This parameter governs the time-dependent recovery rate	1/14 (1/6) 1/day
$D^{*}$	Natural interaction distance	1.2 m
${\beta }^{*}, v,$ and $w$	Intrinsic transmission rate and the contact and airborne transmission adjuster	Calibrated
$\rho$	Current vaccine efficacy, using SinoVac [29]	0.35
${\lambda }_1$	The rate of social resistance in the observed community	0.07 1/day
${\lambda }_2$	The rate of social response in the observed community	0.53 m/day
${\lambda }_3$	Average concentration of airborne pathogens emitted by one infected individual per day	24 quanta/(day $\mathrm{person}·{\mathrm{m}}^3)$ [24]
${\lambda }_4$	Removal rate of airborne pathogens	2 1/day [21]
